When Elle descends into Level 5 to release Noah, Flint attempts to flirt with her. Knox stands silently in a nearby cell. Later, when Elle disables the power grid, opening all cells, Flint asks Knox what their plan is and where they are going.

Knox, Flint, the German and Peter arrive at a bank in Poughkeepsie. Knox senses Peter is scared. As they come in, the German shuts all the windows with his ability, Knox says, "Light", and Flint intimidates the customers. A few minutes later Knox watches them all giving their cell phones, and Flint bags money. A woman reaches for the alarm button, but Flint notices and threatens to rape her. The German opens a safe and wants to leave with money, but Knox kills him and says they will be waiting for the Company instead.

Knox realizes that "Jesse" is an impostor and throws Peter into a wall. He questions Peter about who he is, and Flint punches Peter. Noah enters the bank, offering himself in the exchange of releasing the customers. Knox pushes him into a chair, and Peter accesses Jesse's ability, hurling Flint across the bank. Then he yells at Knox, but the time is stopped. Future Peter comes, gets his present self out of Jesse's body and takes him to the future, resuming time. Now free, Jesse grabs Noah. Sylar comes in and saves the day: Flint is captured, Jesse is killed, and Knox escapes.
